A Phase IIb, Multicentre, Randomised, Double Blind, Placebo Controlled, Three-arm Parallel-group Study to Evaluate the Efficacy, Safety, and Tolerability at Week 24 of 2 Doses of CHF10067 (Zampilimab),in Participants With Idiopathic Pulmonary Fibrosis
The purpose of this study is to evaluate the efficacy, safety, and tolerability at Week 24 of 2 doses of CHF10067 (zampilimab) in participants with idiopathic pulmonary fibrosis (IPF). It is a phase IIb, multicentre, randomised, double-blind, placebo-controlled, three-arm parallel-group study. A total of 240 participants with IPF (Idiomatic Pulmonary Fibrosis) will be randomised in approximately 150 investigational sites in North and Latin America, Europe, Asia, and Oceania.
• Informed consent: Participant's written informed consent obtained prior to any study-related procedure.
• Sex and age: Male or female, of any race and ethnicity, aged ≥40 years with a life expectancy of at least 1 year at screening in the opinion of the Investigator.
• Body weight ≥45 kg.
• Diagnosis of IPF: Diagnosis as defined by the 2018 and 2022 American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Society Guidelines for a maximum 8 years before screening. The most recent High-resolution computed tomography (HRCT) ≤6 months prior to screening, reviewed by central reading, should be used to confirm the diagnosis.
• Lung function: FVC ≥45% of predicted normal value and a ratio of forced expiratory volume in the first second (FEV1)/FVC ≥0.7 at screening.
• Diffusing capacity of the lung for carbon monoxide (DLCO) corrected for haemoglobin ≥25% of predicted normal at screening.
• Oxygen saturation measured by pulse oximetry (peripheral capillary oxygen saturation \[SpO2\]) \>90% at rest when the maximum oxygen flow is 4 L/min by standard nasal cannula or the equivalent oxygen delivery via reservoir nasal cannula (≤2 L/min).
